What it means

The upper oven display is reporting the manual's general function-error pattern; the suffix is not decoded into a specific part.

This explanation is shared only by models whose manufacturer documents the same code, meaning, and guidance.

Touch Clear/Off, let the upper oven cool for one hour, and try operating it again.
If the pattern repeats, disconnect all power for five minutes, reconnect it, and request service if it reappears.
